Termination method: Temperature rise per time interval [dT/dt]

As termination method and/or additional termination method I do wish to add temperature rise per time interval [dT/dt]. For example terminate charging when temperature rises > 1 degree in 1 minute. And (optionally) depending on the precision and noise of the temperature probe: > 0,5 degree in 30 sec...

Termination method: time (14 - 16 hours)

For NiMH (and NiCd) batteries that have been stored for more then 6 months the advice is to cycle them 1 to 3 times, at a charge rate of 0.1C and a time based termination limit of 14 till 16 hours, and at a discharge rate of 0.5C. Otherwise the -dv might not terminate correctly. For this to be used ...

Display average discharge voltage

To get an idea about the discharge curve without actually seeing a graph, it is useful to see the average discharge voltage in any "program" that involves discharging (dcdc, d, dc, etcetera). Having devices that require more then one battery, involves matching a set of almost equal batteries for opt...

Re: Lower charge current when charging is near complete

Less heat development, lower battery temperatures. Temperatures above 25ºC reduce the life of the battery considerable.

Re: MicroView Arduino Brain/Display?

I can only find a charger without a display that is for sale at http://www.paulallenengineering.com/sto ... ducts.html.

What is meant with the "current LCD charger"?

Auto max recycle function: charge/discharge untill there capacity increase is < 10mAh

Instead of having a fixed number of "Charge, then Discharge, Charge" cycles, run it until the capacity this not increase by more then 10 mAh. To make the even more ultimate: when the charger has not been used in the last 4-6 weeks (configurable interval, though this is a good default) instead of "ch...

Lower charge current when charging is near complete

The Opus BT-C700 lowers the charging current when charging is almost complete . Somewhere between 1,45 and 1,50 volt the Opus BT-C700 decides to drop 700 mA charging current to approximately 50% (350 mA) of charge current. At the lower charging rate of 200 mA the charge current drops to an effective...

Start charging without pressing button

Not having used the hardware, only reading the manuals like Quick Start Guide Version 1.1, I'd wish a charger that starts charging as soon as batteries are inserted.
